PoE Power Requirements
PoE Only Modules.
There are two PoE modules for the E5400zl/E8200zl chassis and they have
the same requirement for reserving 22 watts (see above). There are 22 watts
per module that is always held in reserve.
PoE Devices Internal Only (J9306A) Internal and External (J9306A) External Only (J9306A)

PoE/PoE+ for
Switch
E5406zl/
E8206zl
1 - 300 watts
2 - 600 watts
1 -900 watts
2 - 1800 watts
A maximum of
2 internal
power supplies
up to 600 watts
and the
external
source can
provide an
additional 600
watts.
A maximum of
2 internal
power supplies
up to 1800
watts, and the
external
source can
provide an
additional 1800
watts.
The internal power
supply has failed, and
the external source
provides up to 600 watts
or 1800 watts
depending on the
voltage used.
Note that without
internal power the
switch will not be active
since the EPS does not
supply system power.
